Don't know if this suggestion was there before in an own topic.
But what i'd like to see for 2.0. would be complete new dungeons/instances.. that play partly "outside" where you can see the sky etc.
what we have now are only wild caves over and over. what about old ruins, forests or even villages or cities? what we have in offline final fantasys, too.
SE could make a whole scenario where Garleans besiege a village like Al Mhigo (or how the harbour city was called like within the storyline) and you have to fight through it, like in Offline Final Fantasy titles like FFXIII.
in the end an imperator from the garleans..
partly outdoor like for example in FFXII:
FFXII Gilgamesh Dungeon
Dungeons and instances dont have to play always in wild caves.. they could create a complete scenario like in one of the offline FF titles.
be creative SE, think different..
that is what we need for 2.0. to make it appear more interesting and fresh.
an instance could also play in a forest or wherever else... why not?
